Abstract

Chrysopids being efficient predators are used against pests of several important crops (Canard et al., 1984). Techniques for mass rearing of these chrysopids were developed by several workers (Morrison, 1977; Krishnamoorthy and Nagarkatti, 1981; Patel et al., 1987). Elsewhere in the world, detailed studies were conducted on the long term storage of the eggs of chrysopids (Tauber et al., 1993). However, reports on the storage of the eggs of chrysopids are lacking in India. An attempt was made to find out the optimum temperature and age of the eggs of Chrysoperla carnea (Stephens) for short term storage and the results are communicated in this short paper.

Abstract

The value of chrysopids as a biological control agent in IPM programme has been appreciated in recent times. Efforts to mass rear them, investigations on dietary requirements and artificial diets with varying degrees of success have been reported (Hassen and Hagen, 1978; Gautam and Paul, 1987; Vanderzant, 1973).
